The suffix -ed transforms verbs into past tense forms, showing that an action has already been completed. For example, "walk" becomes "walked," indicating the action happened in the past. This fundamental suffix helps students express when events occurred in their narratives and descriptions.
The suffix -ing creates present participles that show ongoing or continuous action. Adding -ing to "paint" creates "painting," which describes an action happening right now. This suffix is essential for expressing current activities and progressive verb forms.
Verb-Creating Suffixes
The suffixes -ize and -ise mean "to make" or "to cause to become." When added to "modern," it creates "modernize," meaning to make something more modern. Similarly, "crystal" becomes "crystallize," meaning to make something resemble a crystal structure.
The suffix -ify typically means "to make" or "to cause." Adding -ify to "quick" creates "quickify," meaning to make something quick. This pattern helps students understand how to transform adjectives into action words with specific meanings.
